摘要

本文研究了HTTP切换对UMTS/HSDPA系统转发链路流量的影响。本研究基于HTTP切换流量接受新标准的引入。这些标准的提出考虑了无线电信号强度(RSS)和缓冲区占用的百分比。此外，本研究结合了数据调度程序Max C/I(最大载波干扰)，PF(比例公平)和新提案Pr/PF(优先比例公平)的接受标准进行。通过对切换流量负载的QoS度量来评估不同的标准和调度器。结果表明，根据所选择的标准和调度器，可以在保证HSDPA系统的QoS的同时，仍然可以接受大量的切换流量。

Impacto do Tráfego Handoff no Sistema 3G UMTS/HSDPA Sob Vários Critérios de Aceitação e Escalonadores

—In this paper is presented a study of HTTP handoff trafﬁc impact in the forward link of UMTS/HSDPA system. This study is based on the introduction of new criteria for HTTP hand-off trafﬁc acceptance. These criteria are proposed considering the radio signal strength (RSS) and percentage of buffer occupation. Moreover, this study is carried out with acceptance criteria combined with data schedulers Max C/I (Maximum Carrier Interference), PF (Proportional Fair) and new proposal Pr/PF (Priority Proportional Fair). Different criteria and schedulers are evaluated through metrics of QoS in function of handoff trafﬁc load. The results showed that depending on the chosen criterion and scheduler, it is possible to assure the QoS of HSDPA system and still to accept a good amount of handoff trafﬁc.
